The eco-climatic region of the Sahel is an area of variable limits that represents the southern edge of the Sahara and the transition area between the desert and the humid tropical zone of Africa. It covers Senegal, Mauritania, Mali, Burkina Faso, Niger and Chad; through 500 kilometers, from the Atlantic Ocean, to the Red Sea.
The dominant economic activity is livestock, while agriculture can only develop in the south more broadly.
Millet is the main subsistence crop along with sorghum, <u><em>while peanuts and cotton are cash crops</em></u>, along with rice that is only grown in irrigated areas.
